Peco II, Inc. — IEEE MA-L assignments; device type Unknown
Summary
- // what this is
- Peco II is registered to MAC prefix
00:90:C1and 1 more in the IEEE OUI database. When a device's MAC address begins with00:90:C1, that block was registered by Peco II — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- RFC 7042 describes 48-bit MAC identifiers as an initial OUI or longer assigned prefix plus remaining bits, and identifies the Group and Local bits in the initial octet.
About this vendor.
A MAC address beginning with 00:90:C1 or 00:15:69 matches an IEEE MA-L assignment to Peco II, Inc.; the available evidence does not identify a device type or product for either prefix.
Each listed prefix is 24 bits long, leaving 24 bits for the remaining address. A match establishes that the address begins with one of these registered prefixes. It does not establish a particular device, product, deployment, or current vendor identity.
For both prefixes, the first byte is 00: its Group bit is 0 and its Local bit is 0. These bit values are fixed for an exact prefix match. Changing either bit changes the prefix, so this interpretation does not imply that variations in those bits are inside the assigned prefix. Each prefix permits 16,777,216 possible suffix values; that is an address-space count, not a count of devices or shipments.
RFC 7042 describes the 48-bit MAC structure and these bit meanings.
